In Soil phosphorus levels under conditions of low level required for the research, in order to identify bacteria supplement root and root hair in low-phosphorus levels under the absorption of phosphorus availability, and whether it will lead to significant role than the objective simulation models a

Must do the supplement research under the soil phosphorus level low condition, verifies the fungus root and the root hair under the low phosphorus level to the phosphorus absorption whether has the remarkable function, whether can cause the phosphorus absorbing capacity which forecasts this objectiv

Low levels of phosphorus in soil under the conditions required for additional research to identify bacteria roots and root hairs on phosphorus uptake at low phosphorus levels have a prominent role, whether objective than this simulation model the forecast will be a large amount of phosphorus uptake
